One of the elements of garden design that designers use is that of structure. While perennials and annuals come and go within a garden accenting it, it is the more permanent aspects of a garden - manmade like arbours or pergolas, or plants like shrubs and trees - that gives it structure, adding strength and often character to a space.

Trees are brilliant structural plants. When our horizontal opportunities are limiting trees allow us to capitalize upon the vertical possibilities often making the space feel bigger. They also add definition to a space too; for instance a single tree planted in the centre of an island bed defines a space in one way but a line of trees along a pathway adds a different dimension cmpletely. The age of a tree can also add a sense of history or context to a garden while the tree itself brings layers of biodiversity to a garden through the different species it supports. All in all a tree's reassuring presence throughout the seasons makes it a first port of call for any garden designer looking to add structure to a garden.
